[Free Registration/Login may be required to access all resource tools.] For this learning module, students are asked to identify which type of quadrilateral matches the description given. Includes video demonstrating a sample problem...

[Free Registration/Login may be required to access all resource tools.] This concept teaches students how to prove that a quadrilateral is a parallelogram given the properties of parallelograms.

[Free Registration/Login may be required to access all resource tools.] Students watch a video overview and attempt practice problems on identifying the properties of squares.

[Free Registration/Login may be required to access all resource tools.] Students watch a video tutorial and attempt practice problems on identifying the properties of rectangles.

In this activity, students will construct angle bisectors and medians in quadrilaterals and explore the properties that appear to be true for four-sided figures. They may find it necessary to review the definitions and properties of...

This activity allows the teacher to cover the properties of a parallelogram, rectangle, rhombus, square, kite, and trapezoid in two days (90 min. block scheduling) Using a group setting students discover these properties using the Cabri...

National Council of Supervisors of Mathematics: Properties of Quadrilaterals provides a teacher learning module on how to effectively teach properties of quadrilaterals and resources that would help to do this.

National Council of Supervisors of Mathematics: Properties of Quadrilaterals provides a geometric design learning module, on how to effectively teach properties of quadrilaterals which is used to develop skills in teachers to aide in...

The tutorial examines the different properties of quadrilaterals. The table consists of picture of the shape and a list of the shape's properties.

Midpoint Quadrilaterals are quadrilaterals that are formed when consecutive midpoints of a quadrilateral are connected. This activity will use Cabri Jr. to investigate what properties an exterior quadrilateral has if its midpoint...

Students construct cyclic quadrilaterals and investigate their properties. They determine which quadrilaterals from the quadrilateral hierarchy are cyclic.

Quadrilaterals-parallelograms, rectangles, and trapezoids-are thoroughly introduced in this lesson plan for upper elementary and middle school students. Lots of resources are linked to it to help support the teacher and students....

In this activity, students construct kites and investigate their properties. They also relate the properties to squares and rhombi.

Use your knowledge of properties of quadrilaterals to correctly match quadrilaterals.

In this activity, students use the tools of Cabri Jr to test their knowledge of geometry. They investigate the properties of the shape formed by connecting the midpoints of adjacent sides of a quadrilateral.

In this activity, students go through the process of proving a quadrilateral to be a parallelogram. They understand the various characteristics of a parallelogram.

For this lesson, middle schoolers explore properties of triangles. They fold paper to make a triangle and measure its angles. Students also draw triangles with given conditions. Included are examples, discussion questions, and closing...

[Free Registration/Login may be required to access all resource tools.] Learn about the Inscribed Quadrilateral Theorem and solve problems involving quadrilaterals inscribed in circles.

Identify quadrilaterals based on pictures or attributes. Quadrilaterals included are parallelograms, rhombuses, rectangles, and squares. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a...

Use the fact that opposite angles in an inscribed quadrilateral are supplementary to solve a few problems. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
